Hi Annette, Ate you still growing the Yacon? I live in the north Florida area, Glen St Mary in Baker county. Are you anywhere near me that I could see how you're growing the Yacon, or that I might have a sprout or two? I may have something to trade if you like. Tim

Gently feel around in the soil to see if you have any tubes.

You can usually get them on trademe but to get tubers this year you would need a plant that's already underway. I have some available most years if you contact me in August.
